Low cost FTTH (FTTH) solutions

Date:2007-03-01

FTTH (Fiber To The Home -- FTTH) access technology for future final, one-plan-fits-all broadband access solutions, in Japan and The United States has been widely used (about 500 million) were users in China, also got more and more attention. As The first domestic specialized is engaged in The Fiber To The home (FTTH) and Fiber To The Desktop (Fiber To FTTD) - The thing equipment research and development production enterprise, we have recently received many FTTH applications, with users in communication and To provide solutions in The process, found that hinder The our country is The biggest obstacle of The development of FTTH investment cost is exorbitant. We think that the correct choice suitable for China's national conditions, development access technology FTTH low cost FTTH access devices is the key FTTH development.

1. The equipment cost excessively high investment benefit low is impeding FTTH development key factors

As is known to all, the price is currently FTTH very costly equipment, often first price $1,000, but in Japan and the United States and other developed countries still receive better development, one of the reasons is its telecom operators may charge a higher service to users. As we have learned, in Japan telecom operators to collect 5,000 - user FTTH monthly service fee, amount to RMB 60 yen about 400, 500 yuan, in the United States each monthly service fee also user FTTH about 80 - $100, of telecommunication network FTTH general 2 -- 3 years can withdraw investment, the benefit of investment is obviously good. But in China, the situation would have been entirely different. At present, many cities in China, because the fierce market competition, ADSL and five types of line based on the LAN broadband access months already down to 50 yuan royalty fee, individual months under higher regions, such as shenzhen, on fees and only 100 yuan. Based on this kind of broadband access service charges level can't support FTTH network construction and operation, investment recovery period of 10 years, so obviously not may arouse investment benefit of telecommunication investment interests. Visible, broadband access market need is of low cost, but the low cost of FTTH will be FTTH applications and development opportunities, but also will have the opportunity of the development. So-called low cost per line should be FTTH less than RMB 2,000 yuan even 1000 yuan, only in this way can only in our country, FTTH mass popularization and development.

2. Conforms to China's reality FTTH access technology

Realize technical scheme FTTH directly determine the manufacturing cost. Equipment FTTH At present, FTTH access technology basically has two kinds big: based on Passive Optical Network (at a Optical PON) access technology -- GPON EPON and, based on the village Active exchange access (Active Optical Fiber AON) - a P2P technology.

Ten years ago, at the beginning of the PON technology was proposed, because fiber very expensive (each core every meters ten yuan even dozens of yuan), and the point-to-multipoint PON P2MP) technology (can effectively save fiber, especially when passive optical distributor is very close to the user's time; Meanwhile PON is passive network, easy maintenance and management. Today, with optical fiber production technology maturity and popularization, cable market price (each core only a few cents per meter already below normal copper cables) the price of the advantage of fiber optic cable, PON saving in today is not outstanding. In addition, our target market is mainly FTTH medium urban residential area resident, urban residential area is commonly garden-like residential area, its outstanding characteristic is: resident, residential area is equipped with high density, communications equipment is mainly used for installation of telecommunication broadband access equipment, and therefore the PON passive network advantage in China cannot give full play to residential and reflect. And the high cost of equipment PON born, bandwidth more users to share, wiring node dispersed, users can't free choice operator, access port utilization rate is low, the network structure is flexible, and other disadvantages, but just is the AON Fiber P2P network structure which can overcome and avoid easily. Special mention PON equipment costs, AON high than many, high costs and become the biggest obstacle PON popularization and application. Therefore, based on the characteristics of residential area in China, we think choosing low-cost community AON active exchange of peer-to-peer (P2P) technology more to China's national conditions.

3. The first Wallace communication low-cost FTTH system

As The first domestic specialized is engaged in The Fiber To The Home (Fiber To The Home -- FTTH) equipment research and development production enterprise, shenzhen Wallace communication technology Co., LTD, fully consider our country market characteristic FTTH, successfully launched with independent intellectual property rights of The accord with China's national conditions and meet The requirements of The low cost OnAccess series products, as FTTH present in our promotion provide FTTH flexible and diversified low-cost FTTH solutions.

 (10) support for the foreseeable future new business: videophone, VOD, digital cinema, telecommuting, online exhibitions, television education, remote medical treatment and data storage and backup, etc.

 (4) the first Wallace communication solutions investment benefit analysis of FTTH

 For broadband access, we assume that the solution FTTH equipment for the average first, the cable cost $1,300 for each information points 500 yuan, where each user investment 1800 yuan; JieRuFei charge users 100 yuan a month, operation and maintenance of such costs on the JieRuFei 50%, which is 50 yuan. So, monthly can profit 50 yuan, take three years recovery, the total investment in the telecommunications industry, the returns in the present should be pretty good.

 And for broadband, CATV and telephone combination of three nets access solutions, we assume that the equipment for 2500 yuan, the average first cable costs 500 yuan for each information points, namely each user investment 3000 yuan; Collect user 100 yuan a month for each month JieRuFei, broadband 50 yuan, a collection of CATV subscriptions CATV cost 400 yuan, operation and maintenance of such costs on the JieRuFei 50%, namely for $75. So, profitable 75 yuan a month, and it's only about 3 years recovery, the total investment returns is also very good.
